Rated 250 VAC, with current depending on the wire gauge used in the mating half. The UL94 V-0 thermoplastic housing suits equipment inside an enclosure where flame rating is required. ## Sourcing and lifecycle status No official replacement or successor has been issued. The base product number is 644695. Compared to the CT series header 1-292164-1, this MTA-100 part has a wider pitch (0.100\" vs 0.079\") and is unshrouded rather than fully shrouded.","metaTitle":"3-644695-4 TE Connectivity MTA-100 Header, 4 Pos, 2.54mm","metaDescription":"3-644695-4 TE Connectivity AMP Connectors MTA-100 unshrouded header, 4 circuits, 0.100\" pitch, tin plating, UL94 V-0.
